Abstract

PURPOSE:To prevent the local pressure fluctuation of an extruder, by using a beaker plate composed of a velocity-leveling block having a number of randomly directed holes each having the same angle to the face of the block, and a straightening block having a number of parallel holes, seriesly connected to the above velocity-leveling block. CONSTITUTION:A breaker plate composed of a velocity-leveling block 1 having a number of randomly directed holes 1a each having the same angle to the face of the block, and having a uniform distribution of holes on both faces, and a straightening block 2 having a number of parallel holes 2a, connected with the velocity- leveling block 1, preferably interposing a pool to stroe the molding material therebetween. EFFECT:Improved uniformity of the molded product.
